CAR-IDIAPI-IRAGM-HOOD CONSTRUCTION.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed May 2, 1914. Serial No. 835,790.

To all whom 'it may cof/wem:

Be it known that 1, CYRUs L. BUNDY, a citizen of the United States, residing at East Orange, in the county of Essex and State of lNew Jersey, have invented certain new and useful Improvements in Car-Diaphragm-l-lood Constructions, of which the following is a specification.

The invention has for its object the provision, in combination with an expansible car diaphragm of the ordinary construction, of a hood or shield therefor to prevent the lodgment thereon of the heavier live coals and hot cinders whereby the diaphragm fabric would be burned and thus destroyed; also to protect material of the diaphragm folds from snow and rain charged with grit which would otherwise fall thereon and enter within the seams rotting the fabric and cutting the threads of the same.

In car construction generally, the flat roof diaphragm as distinguished from the peak roof has been found to be the more desirable, but by reason of the necessity for shedding the snow and rain a lateral pitch has to be given the roof or a supplemental roof or hood provided spaced from and above the roof proper'. These hoods have been made in the same way as the roof, of fabric folded to expand and contract vwith the diaphragm, and have a lateral pitch to discharge the moisture to the sides. It has been demonstrated, however, that the larger live coals falling upon such hoods catch in the folds and burn holes in the fabric thus speedily destroying the usefulness of the same.

According to the present construction a shield or upper hood of metal is arranged abovethe diaphragm roof proper or above the usual type of supplemental roof or hood, if such latter be employed. This metallic shield is hinged at one end and slidably mounted at the other so as to accommodate itself by longitudinal movement to the expansion and contraction of the diaphragm and it preferably has a lateral or longitudinal pitch. The upper surface of the metal shield being smooth, however, cinders falling thereon will not collect in any case but will be blown off by the gusts of air due to the movement of the train and will fall clear of the underlying fabric of the diaphragm.

1n order that the invention and its man ner of application may be readily understood a preferred embodiment of the same isset forth in the accompanying drawing.

and in thesubjoined detailed description based thereon. As, however, the invention is capable of constructional modification within a wide range the drawing and description are to be taken in an illustrative andnot in an unnecessarily limiting sense.

In the drawing-Figure 1 is an end elevation of the upper portion of a railway car having the invention installed therein; Fig. 2 is a side elevation partly in longitudinal vertical section illustrating the mounting of the shield; and Figs. 3 and 4 are views similar to Figs. 1 and 2 respectively, but showing another embodiment of the invention.

Having particular reference tothe first embodiment of the invention illustrated, the face plate of the diaphragm construction is represented at 11, connected by the usual expansible diaphragm with the end plate 12 of the car body indicated generally at 13, the diaphragm comprising the two vertical legs l1 and the horizontal roof 15 made of fabric with bellows folds.

mental roof of fabric as is common, or the roof 15 may itself be omitted. To the face plate 11 along its upper edge is hinged at 16` a metal shield 17 having preferably a smooth upper face. The shield 17 as illustrated', extends at an upward inclination and has its free end 18 slidably mounted within a space 19 and resting upon the inclined surface 20 of the deck end 21 of the car roof, the space 19 being covered by a supplemental deck roof portion 22 between which and the deck roof 2O the free upper end of the shield 17 is housed. The shield 17 has a width coextensive with or slightly greater than the roof 15 of the diaphragm so as to prevent the larger live coals from falling upon the roof proper or supplemental roof of the diaphragm.

It will be observed that as the shield is hinged at one end to the face plate and at its other end is free to slide longitudinally of the car the expansion and contraction of the diaphragmis not interfered with in any degree and the fabric of the diaphragm is protected from the lodgment thereon of hot cinders which would otherwise burn holes Above the roof l5 may or may not be arranged a supplein the same and speedily destroy its usefulness.

That embodiment of the invention illustrated in Figs. 3 and 4 possesses the same ygeneral characteristics as that hitherto deupon'which it slides.

I claim:

LyThe combination in a car diaphragm construction of a metallic shield arranged above the diaphragm roof in spaced relation thereto, said shield flexibly secured at one end and slidable at the other longitu? dinally of the car, substantially as described. 2.' rIhe combination in a car diaphragm construction of a rmetallic shield arranged above the diaphragm roof in spaced relation thereto, said shield hinged at one end and slidable at the other longitudinally of the car, substantially Vas described.

'3. The combination in a car diaphragm construction of a metallic shield arranged abovethe diaphragm roof in spaced relation thereto, said shield hinged at its forward end and slidable relatively to the car at its rearend, substantially as described.

4c. The combination in a car diaphragm construction of a metallic shield arranged above the diaphragm roof in spaced relation thereto, said shield having a downward pitch longitudinally of the car and hinged at its lower end to the face plate of the diaphragm construction and slidable within the car roof at its upper end, substantially as described.

5. The combination in a car diaphragm construction of a metallic shield arranged above the diaphragm roof in spaced relation thereto, said shield having a downward pitch longitudinally of the car and providing near its lower end a transversely eX- tending trough with a lateral pitch, the shield hinged at its lower end to the face plate of the diaphragm construction and slidable at its upper end within a housing upon the car roof, substantially as described.

6. In a car vestibule construction including a car end, a face plate movable relative thereto, and diaphragm side walls extending between the car end and face plate, a metallic cover overlying the space between the car end and face plate and the side walls and separate from said walls, said cover iiexibly secured at one end and slidable at the other longitudinally of the car.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
